Parsing string for date using Javascript

Have a CMD command that returns the user expiration date, to get it into Javascript:

var stringToParse = "You have a doctor's appointment on 2012/03/13 16:00.  Please show up on time.";

var dateString    = stringToParse.match(/\d{4}\/\d{2}\/\d{2}\s+\d{2}:\d{2}/);

var dt            = new Date(dateString);

console.log(dt);        //prints "Tue March 13 16:00:00 EDT 2012"
